Answer:
7cm
Step-by-step explanation:
The radius of the base of the cone is 4.27 cm.
The vertical angle of a cone is also known as the apex angle. The apex angle of a cone is the angle at the top of the cone, where the slant height and the two radii meet.
The formula for calculating the radius of a cone is:
tan(apex angle) = height / radius
In this case, the apex angle is 54°, the height is 6 cm, and we need to find the radius.
tan(54°) = 6 cm / radius
radius = 6 cm / tan(54°)
radius = 4.27 cm
Therefore, the radius of the base of the cone is 4.27 cm.

400 people are asked if they drink tea
7/10 say yes and 20% of the people who say yes drink three cups a day
Answer:
56 people drink 3 cups daily
Step-by-step explanation:
What's the total number of people that drink 3 cups?
Total number of people = 400
7 / 10 were asked said yes
Number of people that said yes = (7 / 10) × 400 = 280
280 people drink tea.
20% of 280 people drink 3 cups daily, whats the number = ?
20% of 280 = ?
20 / 100 = x / 280
(20 × 280) = (100 × x)
5600 = 100x
X = 5600 / 100
X = 56 people
56 people drink 3 cups of tea daily.
Answer:
56 people drink 3 cups daily

find the third angle of a triangle it two of the angles measure 29 degrees and 87 degrees? A) 58 B)64 C) 93 D)116
Answer:
64 degrees
Step-by-step explanation:
Angles in a triangle add up to 180
87 + 29 = 116
Final angle must be 180 - 116 = 64
Answer:
Hello,
B) 64
Step-by-step explanation:
29 + 87 + X = 180
X = 180 - 29 - 87 = 180 - 116 = 64

The width of the base of the mountain defined by the function is 12 feet.
Co ordinatesWhat are co ordinates?a group of variables that accurately depict a position. The first number on a graph represents the distance along, while the second number represents the distance up or down. For instance, the point (2,15) is located 2 units down and 15 units up.
What is Abscissa?The "x" coordinate of a point, as represented on the horizontal line, is another name for the abscissa.
What is Ordinates?The co ordinate that is displayed on the vertical line, commonly known as the "y" coordinate is called ordinates.
Description for the co ordinates (12, 16)As, 12 is written first on the co ordinates, that's why 12 is showing the abscissa on the horizontal line which is the width of the base of the mountain.
While, 16 here shows the ordinates on the vertical line which is the highest point of the mountain.

Hi!
Got a question!
The question is: Find the volume of the shape above(if youre using the app) or below ( if you are using the website ).
Thanks !!
Answer:
404.09x cm³ (to 5 s.f.),
where x is the unknown height of the shape.
Step-by-step explanation:
Volume of the shape
= base area × height
= (large semicircle- small semicircle) × thickness of shape
Area of circle= [tex]\pi {r}^{2} [/tex]
Area of semicircle= [tex] \frac{1}{2} (\pi)( {r}^{2} )[/tex]
Diameter of small circle= 14
Radius= diameter ÷2
radius= 14 ÷2
radius = 7 cm
Area of small semicircle
[tex] = \frac{1}{2} (\pi)( {7}^{2} ) \\ = \frac{49}{2} \pi[/tex]
Radius of large semicircle
= 35 ÷2
= 17.5 cm
Area of large semicircle
[tex] = \frac{1}{2} (\pi)( {17.5}^{2} ) \\ = \frac{1225}{8} \pi[/tex]
Base area of shape
[tex] = \frac{1225}{8}\pi - \frac{49}{2} \pi \\ = \frac{1029}{8} \pi[/tex]
Since the height if the shape is not given, I'm afraid I cant help you find the volume.
Let the height of the shape be x cm.
Volume of shape= [tex] \frac{1029x}{8} \pi \: cm^{3} [/tex]

Monte's Autorana is having an end-of-year clearance in which the TV ads proclaim that
all cars are sold at 5% markup over the dealer's cost. Monte has a new Exfinity for sale
for $18,970. On the Internet, you find out that this particular model has a dealer cost of
$17,500. Is Monte being honest in his advertising?
Answer:
No
Step-by-step explanation:
We first write out $17,500 as a multiplication to 5%
New price = 17500 x 1.05 = 18375 = $18,375
18375-17500 = 875
We then work out the tax on just the mark up of $875 increase
20% mark up = 875 x 0.20 = 175
18.375+175 = 18550
= $18,550 charge to be considered for 5%
However Monte would argue that tax on tax also applies to 875 x 1.20 = 1050
=$1050 and he is just asking to meet half tax costs an extra 10% of his own tax back of 17.500 x 20% that he paid = 17500 x 0.20 = 3500
tax he paid inclusive or non inclusive would be the same.
= $3500
10% of this = 3500 x 0.10 = 350
18550+350 = 18,900
Therefore it is not dishonest if mentioned in the terms and conditions.
We also universally can round 5% up by applying other charges to include promotion costs and even apply more for administration costs.

Solve N = 3rt^4 - 5rz
(solve for z)
Answer:
Step-by-step explanation:
N = 3rt^4 - 5rz
now factor r out
N = r(3t^4-5z)
divide by r on both sides
N/r = (3t^4 - 5z)
subtract (3t^4)
N/r - 3t^4 = -5z
now divide by -5 to isolate the variable (z)
[tex]\frac{(n/r)-3t^4}{-5}[/tex] = z
Answer:
(N-3rt^4) / -5r = z
Step-by-step explanation:
N = 3rt^4 - 5rz
Subtract 3rt^4 from each side
N-3rt^4 = 3rt^4-3rt^4 - 5rz
N-3rt^4 = - 5rz
Divide each side by -5r
(N-3rt^4) / -5r = - 5rz/ -5r
(N-3rt^4) / -5r = z
